Pesticide Companies Want Immunity, Arizona Families Deserve Better

For decades, farmers and consumers across Arizona have relied on pesticides to keep crops productive and lawns manageable. But as the science linking these chemicals to serious illness has grown stronger, so has the legal and political battle over who gets to hold manufacturers accountable, and whether they can be held accountable at all.

A sweeping push for pesticide immunity is gaining ground in legislatures across the country. For Arizonans who have developed cancer, neurological disorders, or other illnesses after pesticide exposure, this debate isn’t abstract — it’s personal.

What Pesticide Exposure Can Do To Your Health

The Environmental Protection Agency (EPA) regulates pesticides in the United States, but even approved products carry health risks. Exposure can happen through food, water, air, or skin contact, and the effects aren’t always immediate.

Short-term exposure may cause headaches, dizziness, nausea, or irritation. But the long-term picture is more alarming. Research has linked chronic pesticide exposure to:

• Cancer, including non-Hodgkin lymphoma
• Neurological disorders
• Hormone disruption
• Respiratory disease

Agricultural workers and rural communities face the heaviest burden, but pesticide residues also turn up in food and drinking water, which means exposure is a concern for nearly everyone.

RoundUp, Glyphosate, and the Science Behind the Lawsuits

The most high-profile pesticide litigation in the country involves glyphosate, the active ingredient in Bayer’s RoundUp weedkiller. Bayer has faced over 170,000 lawsuits from people who say the company failed to warn them about the cancer risk adequately.

Studies in heavily farmed regions have found higher rates of cancer where pesticide use is most intense. A major study that pesticide companies relied on to argue glyphosate was safe was recently withdrawn after investigators discovered the research had been funded — and influenced — by the manufacturers themselves.

Most pesticide-related lawsuits center on one core question: Did the manufacturer adequately warn consumers about the health risks? Pesticide companies say yes, and that EPA label approval should shield them from all further liability.

The Push for Immunity and What It Means for Your Rights

That argument has found a receptive audience in legislatures across the country. States like Georgia and North Dakota have already passed laws protecting pesticide makers from lawsuits when their products carry federally approved labels. Similar legislative proposals are being introduced across the country.

At the federal level, the stakes are even higher. In February 2026, President Trump signed an executive order designating glyphosate-based herbicides as critical to national security under the Defense Production Act — and extending legal protections to companies following federal production directives. Congress is also debating a Farm Bill provision that would create uniform national labeling rules, blocking states from requiring stronger warnings or allowing state-level lawsuits.

In response, public health advocates have introduced the “No Immunity for Glyphosate Act,” which would preserve individuals’ right to sue pesticide manufacturers for harm. The outcome of that fight will shape whether families in Arizona and across the country retain any legal recourse at all.

Until manufacturers are held to a higher standard, protecting yourself starts with how you use these products. If you’re applying pesticides at home or on the job, these precautions from the EPA can help reduce your exposure:

• Use pesticides only when necessary and try non-chemical pest control first.
• Always read and follow the product label, use only the recommended amount, and never apply pesticides for pests not listed on the label.
• Wear protective clothing, wash your hands, and change clothes after use.
• Keep children, pets, toys, and food away during application.
• Avoid spraying in windy or rainy conditions to prevent drift. 
• Dispose of leftover pesticides safely through local hazardous-waste programs.

Your Legal Rights May Be on a Countdown

If you or someone you love has been diagnosed with cancer or another serious illness following prolonged pesticide exposure, there may be a limited window to take legal action, particularly as immunity legislation advances. Which means waiting could be a risk.
